Nick. Posted January 4, 2016 Report Share Posted January 4, 2016 I have 2 V570's that i would like to setup to mirror each other. i have 1 setup with 2 modbus ports (1 & 2) port 1 is connected to a PC via modbus as slave port 2 is connected to another V570 Via modbus as master the second PLC is setup with port 2 as slave I'm to receive data from the pc and have both PLC's make changes to the data and send it back to the pc the first PLC is getting MI 100 - MI 132 and MI 200 - MI 232 and MI 1000 - MI 1045 from the PC and sending the data to the second PLC at the same MI addresses the second PLC is receiving the same MI's from the first PLC and sending the same MI's back the problem I'm having is the PLC'S are sending the same data back and forth before i can make my changes to the data. is there another way of mirroring the two PLC'S together? test slave.vlptest master.vlp Quote Link to comment Share on other sites More sharing options...
